Technical Field

[0001] The utility model relates to the technical field of mold maintenance, in particular to a heavy mold disassembly trolley. Background Art

[0002] After long-term use, a large amount of dirt and grease will accumulate on the mold. Therefore, it is necessary to regularly open the mold for maintenance and cleaning. The traditional way to open the mold is usually to open the upper mold base through a hanging bracket and then clean it. It requires manual flipping of the upper and lower mold bases and cleaning. However, when dealing with heavy molds, the maintenance of this method is difficult and has potential safety hazards. Therefore, a device is needed to be applied to the disassembly and flipping work of heavy molds. Content of the Utility Model

[0003] In order to overcome the deficiencies of the background art, the technical solution adopted by the utility model is: a heavy mold disassembly trolley, including a moving platform, a positioning frame, an adjusting frame, a double lead screw module, a transmission shaft, a turning tooling and a linear module. Two groups of positioning frames / adjusting frames are distributed on both sides of the moving platform through the double lead screw module, and the double lead screw module is provided with a transmission shaft for synchronously controlling the moving amount of the positioning frame and the adjusting frame. The positioning frame and the adjusting frame are connected with a turning tooling for externally connecting the mold, and the adjusting frame is provided with a linear module for adjusting the distance between the turning toolings.

[0004] By adopting the above technical solution, the mold is transferred to the moving platform through a hanging bracket, and one side of the mold is clamped to the positioning frame. The adjusting frame moves to the other side of the mold through the linear module, so that the mold is clamped between the positioning frame and the adjusting frame through the turning tooling. The mold is separated by adjusting the double lead screw module. This device is suitable for carrying molds with a weight not exceeding 1500 kg, and the mold is rotated through the turning tooling, providing great convenience and safety for the disassembly and cleaning work of heavy molds.

The double-threaded lead screw is rotatably connected to the moving platform through the bearing seat. X-axis linear guide rails for laterally transporting the positioning frame / adjusting frame are arranged on both sides of the double-threaded lead screw. The positioning frame / adjusting frame is meshed and connected to both ends of the double-threaded lead screw through the X-axis nut pair.

[0006] Furthermore, the double-threaded lead screw includes a right-handed lead screw and a left-handed lead screw which are coaxially distributed, and the right-handed lead screw is connected to the left-handed lead screw through a coupling.

[0007] By adopting the above technical solution, the first reducer is controlled by the first hand wheel, and the two sets of double-thread screws are simultaneously controlled to rotate by the transmission shaft, so that the two pairs of positioning frames and adjustment frames move synchronously in opposite directions, making it easy to separate the upper and lower mold frames of the mold in parallel.

[0009] By adopting the above technical solution, the second hand wheel is used to control the rotation of the adjusting screw rod, so that the adjusting frame moves toward or away from the positioning frame, which is convenient for installing or disassembling the mold.

[0010] The utility model is further configured that a support frame for assisting in positioning the mold is provided on the mobile platform, the support frame includes a support plate, a Y-axis linear guide and an adapter, the support plate is slidably connected to the adapter via the Y-axis linear guide, and the adapter is slidably connected to the mobile platform via the X-axis linear guide.

[0011] By adopting the above technical solution, when the mold is moved to the mobile platform, the side of the mold is abutted against the support plate, and the support plate moves toward or away from the positioning frame through the Y-axis linear guide to prevent the mold from shaking when suspended in the air, thereby facilitating positioning and assisting installation.

[0013] By adopting the above technical solution, the second reducer is controlled by the third hand wheel to control the rotation of the upper and lower mold frames for easy cleaning and maintenance. The first and second reducers are both worm gear reducers with a self-locking function to prevent the upper and lower mold frames from moving freely, thereby improving the safety of maintenance work.
